The Prophet (ﷺ) said, "Allah did not send any prophet but that he warned his nation of the one-eyed liar (Ad-Dajjal). He is one-eyed while your Lord is not one-eyed, The word 'Kafir' (unbeliever) is written between his two eyes."
Oneness, Uniqueness of Allah (Tawheed)
Sahih al-Bukhari - Hadith 7408
Exposition of the Hadith
This noble hadith establishes fundamental principles of Islamic creed concerning the Dajjal and Allah's perfect attributes. The Prophet's warning about the one-eyed liar serves to protect the ummah's faith from his great tribulations.
The clarification that "your Lord is not one-eyed" affirms Allah's perfection and negates any deficiency from His Essence. Unlike the created Dajjal who lacks an eye, Allah the Exalted is complete in all His attributes, seeing all things without need for physical organs.
The inscription "Kafir" between his eyes manifests Allah's wisdom in making disbelief apparent upon him, serving as a clear sign for believers. This visible marking distinguishes truth from falsehood and aids recognition of this great fitnah.
Scholarly Commentary
Ibn Hajar al-Asqalani explains in Fath al-Bari that every prophet warned his nation about the Dajjal, indicating the universality of this trial and the importance of being prepared through correct belief and righteous deeds.
Al-Qurtubi notes that the Dajjal's one-eyed nature symbolizes his spiritual blindness and deviation from truth, while believers possess the insight of faith that sees reality through Allah's guidance.
Ibn al-Arabi emphasizes that the hadith establishes the principle of Allah's transcendence above physical imperfections, reinforcing the foundation of Tawheed - that nothing resembles Allah in His essence, attributes, or actions.
